Bung Khong Long is a large
lake in the extreme northeast area of Thailand near the Mekong River.

It is also the name of a large
village located at the SE corner of the lake and the name of the district
surrounding the lake area.

Phu Langka National
Park is located on a mountain just a few kilos east of BKL. Hardly any of
the mountain lies within the boundary of BKL, but the visual presence of the
mountain dominates much of the scenery around here.

The official name of the
mountain is Phu Langka, but it is known to the locals as Phu Cao.
